BOTTLE-CLOSURE..

Specification of Letters Patent.

Patented Oct. 17, 1905.

Application flied May l5, 1905. Serial No. 260,516.

To all irl/71,0711, NM1/y concern/ Beit known that I, CHARLES MICHEL DALY, a citizen of the United States, and a resident of the city of New York, borough of ,Manhattan, in the county and State of New York, have invented a new and Improved Bottle- Closure, of which the following' is a full, clear, and exact description.

This invention relates to closures for bottles adapted for preventing' the refilling of the bottles after they havebeen emptied, and thus prevent the reuse of the liquid-holding package after its original contents have been removed therefrom.

The invention consists in the novel construction and combination of parts, as is hereinafr described. and defined in the subjoined claiins.

Reference is to be had to the accompanying drawings, forming a part of` this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of the neck of a bottle, the improved closure thereon, and a preferred means for removing acap-seal from the closure and thus permitting the decanting of the contents of the bottle. Fig. 2 is a longitudinal sectional View of the bottle-neck through its center and of the improved closure device, showing the closure-cap sealed for preventing' leakage from the bottle during Fig. 3 is a nearly-similar View, but showing the sealing means removed from the cap of the closure and the bottle tilted for decanting its contents, the course of the escaping' liquid being indicated by arrowsin said figure. Fig. 4 is a perspective View of the valve-case; and Fig. 5 is a sectional plan view of a cupped flange employed as a detail of the closure, taken substantially on the line 5 5 in Fig. 2.

ln the drawings, 6 indicates the neck of a bottle formed with a shoulder c at a suitable distance from the rounded pouring-lip this being a common constructive detail for bottles used in putting up various liquids for sale as original packages.

rlhe improved closure for the bottle-neck is designed to take the place of a cork or other sealing means and comprises the following details: A cylindrical valve-case 7 is employed that fits closely within the neck 6, and at a suitable point above the end that is inserted in the neck a petticoat-iange 8 is secured on the exterior surface of the valve-case.

As is shown clearly in Figs. 2 and 3, the

petticoat-fiange 8 is joined by its inner edge c upon the side wall of the valve-case and thence curves upward. outward, and then downward, thus providing an annular space c' between the valve-case and the annular curvature c2, that spaces apart the double walls of the petticoat, the outer depending flange 8 of the latter fitting' closely against the exterior surface of the bottle-neck 6 when the concave surface of the curvature ci is seated upon the rounded lip of the bottle-neck.

A plurality of perforations (Z are formed in the wall of the valve-case 7 opposite the upwardly and outwardly lflaring wall of the petticoat-Iiange 8, and at a suitable distance above the perforations (Z a transverse imperforate partitionwall e is secured. A seat g/ is formed on the inner surface of the valvecase 7 at its lower end, and a spherical ballvalve 9 is neatly fitted into the case 7, said valve being introduced before the partitionwall e is secured in place.

It will be noted that sufficient space is afforded between the ball-valve 9 andthe wall e to permit a free passage of liquid through the openings d and into the'space c if the ball-valve is permitted to roll into engagement with said partition-wall, as appears in Fig. 3.

A cupped [lange l() is formed or secured upon the valve-case 7 at a point nearly opposite the plane of the transverse partition e 'and thence curves outward and upward, -terminating at and near the upper edge in an outwardly and dowrnvardly curved rim t.

As shown, a plurality of perfor-ations i are formed in the wall of the valve-case 7, and a similar series of perforations 1i is formed in the cupped flange lO immediately above the partition c, but not opposite the pcrforations f. Aconical cap-piece il, preferably formed of sheet metal, is shaped to [it closely upon the outer edge of the cupped flange l() and seat upon the convex upper surface ofthe rim L.

The length of the coniform cap-piece il is so proportioned that it will extend slightly below the bead or shoulder a on the bottleneck when the valve-case 7 is inserted therein until the curved portion c of the petticoatflange 8 seats upon the pouring-lip L, and the cap-piece is mounted upon the cupped iiange 10.

It will be seen that when the cap-piece l1 is iu position on the cupped flange l() it will incase and have contact with the Vouter sur- IlO face of the petticoat-flange, that in turn incases the portion of the bottle-neck 6 above the shoulder a.. A central perforation is formed in the top wall of the cap-piece 11, through which the upper extremity of the valve-case 7 projects slightly and may be therein secured.

A sealing-disk 12 is mounted upon the upper end of the valve-case 7 and is thereon secured by solder, which does not extend to the edge of the disk, but permits aslight crevice fm to intervene between the disk and top wall of the cap-piece 11, as is shown in Fig. 2.

It is evident that the several parts of the entire closure device hereinbefore described may be assembled ready for service and be applied upon the neck of a bottle upon which it is adapted to lit properly after the bottle has been filled with the liquid it is to contain.

IVhen the cap-piece 11 is forced down over the bottle-neck, the lower edge thereof, which projects slightly below the bead or shoulder t on the bottle-neck, is turned inward and below said shoulder by suitable means, which will secure the complete closure upon the neck of the bottle. In an annular crevice that may be formed between the bead or shoulder (t a suitable cement u may be introduced when the cap-piece is mounted upon the neck of the bottle, and said cement when it hardens will render the joint between the neck 6 and cap-piece 11 liquid-tight, as well as aid in holding the cap-piece from displacement.

The sealing-disk 12, which covers the opening in the top of the valve-case 7, may be removed by means of a furcated lever 18, the application of which is shown in Fig. 1, or by using pliers. Said lever which is preferably employed for the purpose indicated is sharpened on the inner edges of its forked limbs 0 o, that are so spaced apart as to permit the introduction of the limbs endwise into the' crevice m, and thus break the soldered joint between the disk 12 and the top wall of the cap-piece 11, which will afford a free but tortuous passage for liquid from the neck when it is inclined as represented in Fig. 3.

It will be noted that it will be practically impossible to introduce a wire or other instrument into the Valve-case 7 below the ballvalve 9 through the lateral openings in said valve-case and in the cupped iange 10, the relative positions of the perforations t", ef, and (Z being such that a wire or the like would have to have such short bends in it that it could not be passed into the valve-case for holding the valve above the perforations d. Furthermore, it will be obvious that the peculiar formation of the petticoatfiange 8, that affords the narrow space c for the passage of liquid from the perforations d, greatly contributes to the security of the device.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A closure for bottles comprising a valvecase, a petticoat extended in inverted-U shape around the valve-case, a ball-valve in the case, means for holding the ball-valve from escape at the lower end of the valve-case, said case having perforations therein opposite the adjacent wall of the annular petticoat, a transverse partition in the valve-case above said perforations, other perforations being formed in the casingwall above said partition, a cupped i'iange on the valve-case near its upper end and having perforations therein, a cap mounted upon the upper extremity of the valve-case that extends therethrough, said cap being securable on the neck of a bottle wherein the valve-case is placed, and means for temporarily sealing the open upper end of the valve-case.

2. A closure for bottles comprising a cylindrical valve-case, a seat within the case at its lower end, an annular inverted-U-shaped petticoat secured by one depending edge on the valve-case above its lower end, said petticoat incasing the upper end of the bottle-neck that receives the valve-case, said case having perforations therein opposite an annular space between it and an ujiwardly-trending member of the petticoat, a ball-valve neatly fitting in the valve-case and movable therein above the seat, a transverse imperforate partition in the valve-case a distance above the perforations therein, a cupped flange secured on the valvecase and spaced therefrom, said flange and the valve-case having opposed perforations therein, a cappiece having coniform shape and a perforate top, said cap-piece fitting over the free edge of the cupped tlange and also contacting with the outer depending' wall of the petticoat, the lower edge of the cap-piece being' bent inward for engagement with a shoulder on the neck of a bottle wherein the valve-case is inserted, and means for temporarily closing the upper end of the valve-case.

3. In a device of the character described, the combination with a tubular valve-case, and a perforate cap-piece securable on a bottle-neck, of a sealing-disk mounted over the open upper end of the valve-case and soldered on the cap-piece but leaving' a free edge and also leaving a crevice for engagement of a tool for displacing the sealing-disk.

In testimony whereof I have signed my name to this speciiication in the presence of two subscribing witnesses.
